Mohammed S, Haidar J, Ayele BA, Yifru YM. Post-stroke limitations in daily activities: experience from a tertiary care hospital in Ethiopia. BMC Neurol 2023; 23:364. [PMID: 37814255 PMCID: PMC10561502 DOI: 10.1186/s12883-023-03419-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Accepted: 10/05/2023] [Indexed: 10/11/2023] Open
Abstract
BACKGROUND The disability of stroke patients remains an important global health problem; yet information on the extent of restriction from basic and instrumental activities of daily living is limited, particularly in lower-and middle-income (LMIC) countries. Therefore, we examined the issue under the caption, since it is the first step in planning several rehabilitation services. METHOD A facility-based cross-sectional study was done to assess the magnitude and predictors of post-stroke limitations in basic activities of daily living (BADL) using the Barthel Index (BI) scale and instrumental activities of daily living (IADL) using the Frenchay Activities Index (FAI) scale among patients who visited Tikur Anbessa Specialized Hospital in Addis Ababa, Ethiopia, Neurology Clinic from April-October, 2022. All patients having a diagnosis of stroke for more than six months duration were enrolled. Descriptive and inferential statistical analyses were done, and measures of estimated crude and adjusted odds ratio with 95% CI were constructed and a p-value less than 0.05 was considered statistically significant. The results are presented in figures and tables. RESULTS A total of 150 stroke patients were enrolled in the present study. The mean age of participants was 53 (14.9) years with slight male preponderance (51.3%). Ischemic stroke was present in 106 (70.7%) of them, while 44 (29.3%) had hemorrhagic stroke. Of this, 57 (38%) and 115 (79.3%) of them had limitations in basic and instrumental ADL, respectively. Comorbid cardiac disease (AOR = 6.9; 95%CI = 1.3-37.5) and regular substance use (AOR = 11.1; 95%CI = 1.1-115) were associated with limitations in BADL, while an increase in age (AOR = 1.1; 95%CI = 1.04-1.15) was associated with severe limitations in BADL. Initial stroke severity (AOR = 7.3; 95%CI = 1.2-44.7) was associated with limitations in IADL, whereas depression (AOR = 5.1; 95%CI = 1.1-23.2) was identified as a predictor of severe limitation in IADL. CONCLUSION Limitation in activities of daily living (ADL) after stroke is common among Ethiopian patients. Therefore, screening for post-stroke limitations in daily activities is essential for further management and rehabilitative plans.

Kelty E, Havard A, Preen DB. Trends in smoking during pregnancy stratified by the use of opioid agonist therapy and the contribution of smoking to poor outcome in neonates prenatally exposed to opioid agonist treatment. Arch Womens Ment Health 2023:10.1007/s00737-023-01342-z. [PMID: 37368055 DOI: 10.1007/s00737-023-01342-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Accepted: 06/17/2023] [Indexed: 06/28/2023]
Abstract
High rates of cigarette smoking have been observed in pregnant women on opioid agonist therapy (OAT). However, it is unclear if these rates have changed overtime in line with the general population and the degree to which smoking contributes to poor outcomes in neonates born to women on OAT. Women who gave birth in Western Australia (WA) between 2003 and 2018 were identified from whole-population midwives records. Linked records were used to identify women who had been dispensed OAT during pregnancy and those who had smoking during pregnancy. Temporal changes in smoking during pregnancy were examined for women on OAT (n = 1059) and women not on OAT (n = 397,175) using Joinpoint regression. In women treated with OAT during pregnancy, neonatal outcomes were compared between smoking and non-smoking women using generalised linear models. During the study period, 76.3% of women on OAT smoked during pregnancy compared with 12.0% of the general population. There was a decrease in the prevalence of smoking during pregnancy among women not on OAT (APC: - 5.7, 95%CI: - 6.3, - 5.2), but not in women on OAT (APC: 0.8, 95%CI: - 0.4, 2.1). For women receiving OAT, smoking was associated with an increased odds of low birth weight (OR: 1.57, 95%CI: 1.06, 2.32) and neonatal abstinence syndrome (OR: 1.34, 95%CI: 1.01, 1.78) compared with non-smoking. Despite reductions in the prevalence of smoking during pregnancy in the general population, similar reductions have not occurred in pregnant women on OAT. The high prevalence of smoking in pregnant women on OAT is contributing to poor neonatal outcomes.

Association Between Chronic Hepatitis C Virus Infection and Esophageal Cancer: A Systematic Review and Meta-analysis. J Clin Gastroenterol 2022; 56:55-63. [PMID: 33780211 DOI: 10.1097/mcg.0000000000001532] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 02/15/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Chronic hepatitis C virus (HCV) infection is associated with increased risk of hepatobiliary tract cancer. However, whether chronic HCV infection is also associated with elevated risk of other types of cancer is still unknown. This systematic review and meta-analysis was conducted in order to investigate whether chronic HCV infection is positively associated with esophageal cancer. METHODS A systematic review was conducted using Embase and MEDLINE databases from inception to November 2019, with a search strategy that comprised the terms for "hepatitis C virus" and "cancer." Eligible studies were cohort studies consisting of patients with chronic HCV infection and comparators without HCV infection, and followed them for incident esophageal cancer. Hazard risk ratio, incidence rate ratio, relative risk or standardized incidence ratio of this association were extracted from each eligible study along with their 95% confidence intervals and were combined to calculate the pooled effect estimate using the random effect, generic inverse variance method. RESULTS A total of 20,459 articles were identified using this search strategy. After 2 rounds of independent review, 7 studies satisfied the inclusion criteria and were included in the meta-analysis. Chronic HCV infection was significantly associated with a higher incidence of esophageal cancer with the pooled relative risk of 1.61 (95% confidence interval: 1.19-2.17; I2=39%). The funnel plot was relatively symmetric which was not suggestive of publication bias. CONCLUSION This systematic review and meta-analysis demonstrated that there is a modest association between chronic HCV and incident esophageal cancer. However, more studies are needed to investigate the causality of this association.

Abstract
Objectives: Concurrent abuse of cocaine and nicotine is considered a public health problem. To date, no effective therapy has been known to reduce the reinforcing effects of concurrent use of cocaine and nicotine. Mirtazapine, an antagonist of the α2-adrenoceptor and the 5-HT2A/C and the 5-HT3 receptors has proven effective in reducing the cocaine, nicotine and methamphetamine behavioural effects in humans and animals. Our study evaluated the effect of mirtazapine on enhancing locomotor activity during the induction and expression of locomotor sensitisation induced by a cocaine + nicotine mixture.Methods: Wistar rats were dosed with cocaine, nicotine or cocaine + nicotine combination. Mirtazapine (30 mg/kg, i.p.) was administered during the extinction phase.Results: Mirtazapine decreased cocaine + nicotine-induced locomotor activity and induction and expression of locomotor sensitisation. In addition, we found that co-administration of mecamylamine and mirtazapine significantly enhanced the effect of mirtazapine on cocaine + nicotine-induced locomotor activity during induction and expression of behavioural sensitisation.Conclusions: Our results suggest that mirtazapine demonstrated efficacy in decreasing the psycho-stimulant effects of concurrent use of cocaine and nicotine.

Abstract
BACKGROUND The prevalence of tobacco cigarette smoking in the US has declined to approximately 15%, yet, it remains over 90% among individuals with opioid use disorder regardless of whether they are currently using opioids illicitly or as opioid substitution therapy. This disparity raises the question of whether opioids facilitate smoking among individuals with opioid use disorder and whether opioid antagonists may reduce it. OBJECTIVES Determine whether injectable extended-release naltrexone (XR-NTX) treatment of opioid use disorder patients is associated with a spontaneous smoking reduction. We hypothesized that treatment with XR-NTX for would lead to a reduction in smoking in tobacco cigarette smokers with opioid use disorder. METHODS We analyzed data from 64 tobacco cigarette smokers (38% female) with opioid use disorder who were induced on XR-NTX for prevention of relapse to opioids. The number of cigarettes smoked per day and opioid-related craving and withdrawal were assessed at baseline and during treatment. RESULTS Smoking was reduced from 14.4 ± 1.0 to 9.8 ± 1.0(p < 0.001) cigarettes per day after one month and 8.6 ± 1.1 cigarettes per day after two months of treatment. Daily cigarette consumption was positively correlated with the pre-treatment frequency of opioid use and opioid-related craving during the XR-NTX treatment. CONCLUSIONS XR-NTX treatment in smokers with opioid use disorder was associated with a 29% decline in daily cigarette consumption. Together with prior evidence of increased smoking during opioid agonist therapy, our finding suggests a pharmacodynamic interaction between nicotine and opioid systems that could influence treatment choices in this population. Our findings merit confirmation in a prospective controlled study. (NCT02324725 and NCT01587196).

Abstract
Cocaine-related deaths occur regularly in forensic routine work. In cases in which the detected concentration of cocaine is rather low and other causes of death apart from intoxication can be ruled out, the question arises if adulterants of cocaine might have played a crucial role. In the present study, cardiac effects of cocaine, of the adulterant levamisole and of mixtures of both were evaluated using the isolated perfused Langendorff heart. While exposed to the substances, functional parameters heart rate, left ventricular pressure and coronary flow were documented. Relevant alterations of these parameters were found for cocaine as well as for levamisole. Exposing the hearts to a mixture of both resulted in a combination of these effects; the emergence of new alterations or an obvious aggravation were not detected. Nevertheless, the results imply that the consumption of cocaine adulterated with levamisole bares an increased risk for cardiac complications, especially in the presence of preexisting cardiac pathologies.

Estimating the impact of drug use on US mortality, 1999-2016. PLoS One 2020; 15:e0226732.

Abstract
The impact of rising drug use on US mortality may extend beyond deaths coded as drug-related to include excess mortality from other causes affected by drug use. Here, we estimate the full extent of drug-associated mortality. We use annual death rates for 1999–2016 by state, sex, five-year age group, and cause of death to model the relationship between drug-coded mortality—which serves as an indicator of the population-level prevalence of drug use—and mortality from other causes. Among residents aged 15–64 living in the 50 US states, the estimated number of drug-associated deaths in 2016 (141,695) was 2.2 times the number of drug-coded deaths (63,000). Adverse trends since 2010 in midlife mortality are largely attributable to drug-associated mortality. In the absence of drug use, we estimate that the probability of dying between ages 15 and 65 would have continued to decline after 2010 among men (to 15% in 2016) and would have remained at a low level (10%) among women. Our results suggest that an additional 3.9% of men and 1.8% of women died between ages 15 and 65 in 2016 because of drug use. In terms of life expectancy beyond age 15, we estimate that drug use cost men 1.4 years and women 0.7 years, on average. In the hardest-hit state (West Virginia), drug use cost men 3.6 and women 1.9 life years. Recent declines in US life expectancy have been blamed largely on the drug epidemic. Consistent with that inference, our results imply that, in the absence of drug use, life expectancy at age 15 would have increased slightly between 2014 and 2016. Drug-associated mortality in the US is roughly double that implied by drug-coded deaths alone. The drug epidemic is exacting a heavy cost to American lives, not only from overdoses but from a variety of causes.

The association between alcohol, marijuana, illegal drug use and current use of E-cigarette among youth and young adults in Canada: results from Canadian Tobacco, Alcohol and Drugs Survey 2017. BMC Public Health 2019; 19:1208. [PMID: 31477067 PMCID: PMC6721192 DOI: 10.1186/s12889-019-7546-y] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Accepted: 08/25/2019] [Indexed: 12/11/2022] Open
Abstract
Background E-cigarettes have grown in popularity around the world since 2003. Although marketed as a smoking cessation tool, e-cigarettes can lead to tobacco cigarette smoking in youth. In Canada, among all age groups, youth and young adults have the highest prevalence of e-cigarette use. The objective of this study was to assess the factors associated with e-cigarette use among youth and young adults in Canada, and to specifically examine the association between alcohol, marijuana and illicit drug use. Methods Data from the 2017 Canadian Tobacco, Alcohol and Drugs Survey were used. The sample was restricted to those aged 15–24 years (n = 10,322), and main outcome defined as ‘E-cigarette use in the past 30-days’. Multivariable logistic regression was performed to assess the association between the main outcome and substance use variables (illicit drug, marijuana and alcohol use), tobacco exposure variables, and demographic and health-related factors. Results 6.2% Canadians aged 15–24 reported using e-cigarettes in the past 30-days, while 23.9% reported having ever tried e-cigarettes. Twenty-three percent of the past 30-day users reported using e-cigarettes every day and 72.5% of the past 30-day users reported having nicotine in their last e-cigarette. Additionally, youth aged 15–17 were 4.95 times more likely to be e-cigarette users as compared to those aged 22–24 (OR: 4.95, 95% CI: 3.1–7.9). Moreover, e-cigarette use was significantly associated with marijuana use (OR:4.17, 95% CI: 2.6–6.7) and alcohol use (OR: 5.08, 95% CI: 2.9–9.0), and approached significance with illicit drug use (OR: 1.68, 95% CI: 1.0–2.9). Furthermore, being a current smoker (OR: 2.93, 95% CI: 1.8–4.7) and male (OR: 2.28, 95% CI: 1.5–3.4) was significantly associated with the outcome. Conclusion This study is nationally representative and provides insight into e-cigarette use among youth and young adults aged 15–24 years. Given that e-cigarettes can be used as illicit drug delivery systems, more studies are needed to understand how Canadian youth and young adults are using e-cigarettes. Stricter restrictions on public e-cigarette smoking, and awareness campaigns informing youth of risks of e-cigarette smoking should be implemented.

Abstract
OBJECTIVES To assess the prevalence of smoking and drug use among adolescent boys, and to examine adolescents' psychosocial factors, and suicidal behaviors associated with adolescents' substance use. METHODS The Kuwait Global School-Based Student Health Survey employed a two-stage cluster sample design targeting a representative sample of adolescents. This study focused on the participated 1310 boys. Statistical analysis included Chi-square test, student t-test, and multivariate analysis. RESULTS The mean age was 14.5 ± 0.03 years. The reported prevalence of: smoking, ever drug use, and both smoking and drug use were 26.6% (95% CI:24.2-29.1%) and 7.4% (95% CI:6.1-9.0%) and 5.5% (95% CI:4.4-6.9%) respectively. Logistic regression model analysis revealed that adolescents whose parents smoke, suffered from insomnia, were victims of bullying, and had negative social school environment, were more likely than others to be smokers, drug users or both. Addendum, suicidal ideation, and its combination with suicidal planning and/or suicidal attempt were significantly associated with smoking. The odds of these life-threatening behaviors increased when drug use was reported and augmented when both smoking and drug use were experienced. CONCLUSIONS Prevalence of smoking and illicit drug use were high among adolescent boys. This study confirmed the association between adolescents' smoking and substance use with psychosocial context, and suicidal behaviors. Addressing these predictors would be crucial in the development of effective strategies targeting the prevention of smoking and substance use, which might consequently reduce suicidal behaviors among adolescents.

Abstract
Young adults are among the greatest consumers of sugar sweetened beverages, and they also have high smoking rates. However, few studies address the relationship between these risk behaviors; this study examined the relationship between soda consumption and smoking among young adult bar patrons, a high-risk understudied population. A cross-sectional survey of young adult bar patrons (between January 2014 and October 2015) was conducted using randomized time location sampling (N = 8712) in Albuquerque, NM, Los Angeles, CA Nashville, TN, Oklahoma City, OK, San Diego, CA, San Francisco, CA, and Tucson, AZ. The survey found the prevalences of daily regular soda intake ranged from 32% in San Diego to 51% in Oklahoma City and current smoking ranged from 36% in Los Angeles, CA to 49% in Albuquerque, NM. In multinomial multivariate models with no soda consumption as the reference group and controlling for demographics and location, non-daily (OR = 1.24, 95% CI = 1.05, 1.47) and daily smokers (OR = 1.34, 95% CI = 1.08, 1.66) were both more likely to drink regular soda compared to not drinking any soda. No effects were found for diet soda consumption. These linked risks suggest that comprehensive health promotion efforts to decrease sugar sweetened beverage consumption and tobacco use, among other risky behaviors, may be effective in this population. Young adult (YA) bar patrons who smoke consume more regular soda than nonsmokers. Being a non-daily or a daily-smoker increased odds of drinking regular soda. Prevalence of smoking among YA bar patrons who were regular soda drinkers varied by region. YA bar patrons attending or graduated from college were less likely to drink soda.

Abstract
BACKGROUND Sleep disturbance is common and may adversely affect treatment outcome, mental health, and quality of life in heroin-dependent patients. Previous studies have focused upon patients receiving treatment. We conducted a cross-sectional descriptive study to explore the 1-month prevalence of sleep disturbance and its associations with socio-demographic, substance-related characteristics, severity of dependence, severity of depression, and quality of life among heroin-dependent patients before entering treatment program. METHODS The sample (n = 514) comprised individuals with heroin dependence attending the methadone maintenance treatment program and the therapeutic community at a psychiatric center in Nantou, Taiwan between 2008 and 2014. Sleep quality was measured using Pittsburgh Sleep Quality Index (PSQI) with a global score greater than 5 indicating sleep disturbance. Centre for Epidemiologic Studies Depression Scale, Severity of Dependence Scale, and World Health Organization Quality of Life-BREF were also approached. T-test, chi-square tests, and multivariate logistic regression were performed to measure associations between variables and sleep disturbance. RESULTS The 1-month prevalence of sleep disturbance (PSQI > 5) was 76.3% among 514 subjects with heroin dependence. Heroin users with sleep disturbance had significantly more life events in the previous year, higher rate of unemployment, greater cigarette consumption, more substance related criminal convictions, longer length of heroin use, higher rate of injectors, greater severity of dependence, greater severity of depression, and lower quality of life compared to those without sleep disturbance. Severity of dependence, severity of depression, and physical health domain of quality of life remained significantly associated with sleep disturbance after adjusting for other variables. CONCLUSION Heroin-dependent patients had a high 1-month prevalence of sleep disturbance, and this was associated with greater severity of dependence, greater severity of depression, and poorer physical health-related quality of life. Early assessments and interventions for sleep disturbance among patients with heroin dependence are recommended.

Walker ER, Pratt LA, Schoenborn CA, Druss BG. Excess mortality among people who report lifetime use of illegal drugs in the United States: A 20-year follow-up of a nationally representative survey. Drug Alcohol Depend 2017; 171:31-38. [PMID: 28012429 PMCID: PMC5263065 DOI: 10.1016/j.drugalcdep.2016.11.026] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2016] [Revised: 10/28/2016] [Accepted: 11/21/2016] [Indexed: 10/20/2022]
Abstract
OBJECTIVE The purpose of this study was to determine the mortality risks, over 20 years of follow-up in a nationally representative sample, associated with illegal drug use and to describe risk factors for mortality. METHODS We analyzed data from the 1991 National Health Interview Survey, which is a nationally representative household survey in the United States, linked to the National Death Index through 2011. This study included 20,498 adults, aged 18-44 years in 1991, with 1047 subsequent deaths. A composite variable of self-reported lifetime illegal drug use was created (hierarchical categories of heroin, cocaine, hallucinogens/inhalants, and marijuana use). RESULTS Mortality risk was significantly elevated among individuals who reported lifetime use of heroin (HR=2.40, 95% CI: 1.65-3.48) and cocaine (HR=1.27, 95% CI: 1.04-1.55), but not for those who used hallucinogens/inhalants or marijuana, when adjusting for demographic characteristics. Baseline health risk factors (smoking, alcohol use, physical activity, and BMI) explained the greatest amount of this mortality risk. After adjusting for all baseline covariates, the association between heroin or cocaine use and mortality approached significance. In models adjusted for demographics, people who reported lifetime use of heroin or cocaine had an elevated mortality risk due to external causes (poisoning, suicide, homicide, and unintentional injury). People who had used heroin, cocaine, or hallucinogens/inhalants had an elevated mortality risk due to infectious diseases. CONCLUSIONS Heroin and cocaine are associated with considerable excess mortality, particularly due to external causes and infectious diseases. This association can be explained mainly by health risk behaviors.

Abstract
BACKGROUND Alcohol use disorders and tobacco use contribute significant risk to the global burden of disease, and each are major public health concerns. Together, alcohol and tobacco use are highly comorbid and have multiplicative health risks when used concurrently, underscoring the importance of examining alcohol-tobacco interactions in the human laboratory. OBJECTIVE The aims of this review were to summarize the state of research examining alcohol-tobacco interactions in the human laboratory. METHODS We reviewed human laboratory evidence for alcohol and tobacco/nicotine interactions, including 1) craving in drinkers and smokers exposed to smoking or drinking cues, 2) fixed-dosing of alcohol or nicotine in smokers and drinkers, and 3) smoking and alcohol influences on self-administration behaviors. The interactive effects of tobacco/nicotine with other drugs of abuse are also briefly discussed. RESULTS Overall, results identified that alcohol and tobacco have reciprocal influences on potentiating craving, subjective responses to fixed-dose alcohol or nicotine administration, and self-administration. The literature identified that alcohol increases craving to smoke, decreases time to initiate smoking, and increases smoking self-administration. Similarly, tobacco and nicotine increase alcohol craving, decrease subjective effects of alcohol, and increase alcohol consumption. CONCLUSION Future studies should continue to focus on alcohol and tobacco/nicotine interactions in individuals with a wide scope of drinking and smoking histories, different states of alcohol and nicotine deprivation, and influences of either drug on craving, subjective responses, and consumption over the course of the blood alcohol curve. This work could have important implications for the impact of alcohol-tobacco interactions on guiding clinical practice, as well as in the changing landscape of addiction.

Abstract
BACKGROUND Alcohol use is prevalent among populations of persons that use illicit drugs. Problematic alcohol use among persons that use heroin and cocaine has been associated with poor treatment adherence, abstinence maintenance, and mental health concerns. Fully exploring how alcohol use severity interacts with route of administration (ROA) may be of notable importance in development of treatment protocols for persons that use heroin and cocaine. METHODS Data from a neurological and sociobehavioral assessment of risk factors among injection and noninjection drug users known as the NEURO-HIV Epidemiologic Study was used in the analyses. Participants (N = 551) included those who reported their level of past-30-day alcohol use and past-6-month heroin and cocaine use. RESULTS Multiple logistic regression analyses found that both problematic and moderate alcohol users were significantly less likely than abstainers to report injecting heroin and cocaine. Both problematic and moderate alcohol users were significantly more likely than abstainers to snort substances. CONCLUSIONS Alcohol use may play a role in promoting or impeding the use of substances through certain ROAs. Treatment protocols that transition persons that use injection heroin and cocaine to noninjection use of these substances may be used in conjunction with treatments that reduce alcohol consumption as a means to reduce noninjection drug use.

Mortality among heroin users and users of other internationally regulated drugs: A 27-year follow-up of users in the Epidemiologic Catchment Area Program household samples. Drug Alcohol Depend 2015; 156:104-111. [PMID: 26386826 PMCID: PMC4787597 DOI: 10.1016/j.drugalcdep.2015.08.030] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2015] [Revised: 08/27/2015] [Accepted: 08/28/2015] [Indexed: 11/17/2022]
Abstract
BACKGROUND In contrast to research on more restricted samples of drug users, epidemiological studies open up a view of death rates and survivorship of those who have tried heroin a few times, with no acceleration toward sustained use patterns often seen in treatment and criminal justice samples. At their best, epidemiological estimates of heroin effects on risk of dying are not subject to serious selection biases faced with more restricted samples. METHODS Data are from 7207 adult participants aged 18-48 years in United States Epidemiologic Catchment Area Program field surveys, launched in 1980-1984. US National Death Index (NDI) records through 2007 disclosed 723 deaths. NDI enabled estimation of heroin-associated risk of dying as well as survivorship. RESULTS Estimated cumulative mortality for all 18-48 year old participants is 3.9 deaths per 1000 person-years (95% confidence interval, CI=3.7, 4.2), relative to 12.4 deaths per 1000 person-years for heroin users (95% CI=8.7, 17.9). Heroin use, even when non-sustained, predicted a 3-4 fold excess of risk of dying prematurely. Post-estimation record review showed trauma and infections as top-ranked causes of these deaths. CONCLUSIONS Drawing strengths from epidemiological sampling, standardized baseline heroin history assessments, and very long-term NDI follow-up, this study of community-dwelling heroin users may help clinicians and public health officials who need facts about heroin when they seek to prevent and control heroin outbreaks. Heroin use, even when sporadic or non-sustained, is predictive of premature death in the US, with expected causes of death such as trauma and infections.

Abstract
BACKGROUND High smoking prevalence has been observed among those misusing other substances. This study aimed to establish smoking behaviours and attitudes towards nicotine dependence treatment among clients and staff in substance abuse treatment settings. METHODS Cross-sectional questionnaire survey of staff and clients in a convenience sample of seven community and residential addiction services in, or with links to, Europe's largest provider of mental health care, the South London and Maudsley NHS Foundation Trust. Survey items assessed smoking behaviour, motivation to quit, receipt of and attitudes towards nicotine dependence treatment. RESULTS Eighty five percent (n = 163) and 97% (n = 145) response rates of clients and staff were achieved. A high smoking prevalence was observed in clients (88%) and staff (45%); of current smokers, nearly all clients were daily smokers, while 42% of staff were occasional smokers. Despite 79% of clients who smoked expressing a desire to quit and 46% interested in receiving advice, only 15% had been offered support to stop smoking during their current treatment episode with 56% reported never having been offered support. Staff rated smoking treatment significantly less important than treatment of other substances (p < 0.001), and only 29% of staff thought it should be addressed early in a client's primary addiction treatment, compared with 48% of clients. CONCLUSIONS A large unmet clinical need is evident with a widespread failure to deliver smoking cessation interventions to an extraordinarily high prevalence population of smokers in addiction services. This is despite the majority of smokers reporting motivation to quit. Staff smoking and attitudes may be a contributory factor in these findings.

An investigation of cigarettes smoking behavior and nicotine dependence among Chinese methamphetamine users in two provinces. BIOMED RESEARCH INTERNATIONAL 2014; 2014:175205.

Abstract
Objective. To survey cigarette behaviors and nicotine dependence among Chinese MA users, explore risk factors for high nicotine dependence, and analyze the relationship between nicotine dependence and MA-related euphoria and sexual impulse. Methods. A cross-sectional study, applying a self-designed questionnaire with the Fagerström Test for Nicotine Dependence (FTND) and Visual Analog Scale (VAS), was performed among 391 MA users in Beijing and Guangdong, China. Results. Most MA users were smokers, including 159 having high dependence on nicotine (HD users, FTND > 5) and 197 low or medium dependent (LMD users, FTND ≤ 5). Men or married users were more likely to be highly dependent than women or unmarried users. Higher MA dose and ever-use of ketamine or alcohol were associated with higher likelihood of high nicotine dependence. HD users reported significantly higher euphoria and stronger sexual impulse after using MA, indicated by higher VAS scores. Conclusions. Potential risk factors for high nicotine dependence among MA users may include male gender, being married, higher MA dosage, and ever-use of ketamine or alcohol, which should be taken into consideration in individualized health promotion on smoking cessation. Severe nicotine dependence was associated with stronger MA-related euphoria and sexual impulse and it should be confirmed by further studies.

Abstract
BACKGROUND AND OBJECTIVES The relationship between substance use and cognitive deficits is complex and requires innovative methods to enhance understanding. The present study is the first to use LCA to examine associations of drug use patterns with cognitive performance. METHODS Cocaine/heroin users (N = 552) completed questionnaires, and cognitive measures. LCA identified classes based on past-month drug use and adjusted for probabilities of group membership when examining cognitive performance. Latent indicators were: alcohol (ALC), cigarettes (CIG), marijuana (MJ), crack smoking (CS), nasal heroin (NH), injection cocaine (IC), injection heroin (IH), and injection speedball (IS). Age and education were included as covariates in model creation. RESULTS Bootstrap likelihood ratio test (BLRT) supported a 5-class model. Prevalent indicators (estimated probability of over 50%) for each class are as follows: "Older Nasal Heroin/Crack Smokers" (ONH/CS, n = 166.9): ALC, CIG, NH, CS; "Older, Less Educated Polysubstance" (OLEP, n = 54.8): ALC, CIG, CS, IH, IC, and IS; "Younger Multi-Injectors" (MI, n = 128.7): ALC, CIG, MJ, IH, IC, and IS; "Less Educated Heroin Injectors" (LEHI, n = 87.4): CIG, IH; and "More Educated Nasal Heroin" users (MENH, n = ALC, CIG, NH. In general, all classes performed worse than established norms and older, less educated classes performed worse, with the exception that MENH demonstrated worse cognitive flexibility than YMI. DISCUSSION AND CONCLUSIONS This study demonstrated novel applications of a methodology for examining complicated relationships between polysubstance use and cognitive performance. SCIENTIFIC SIGNIFICANCE Education and/or nasal heroin use are associated with reduced cognitive flexibility in this sample of inner city drug users.

Abstract
Transformations of cocaine and eleven of its metabolites were investigated in untreated municipal sewage at pH ≈ 7 and 9, 23, and 31 °C. Results indicated that hydrolysis-possibly bacterially mediated-was the principal transformation pathway. Residues possessing alkyl esters were particularly susceptible to hydrolysis, with pseudo-first-order rate constants varying from 0.54 to 1.7 day(-1) at 23 °C. Metabolites lacking esters or possessing only a benzoyl ester appeared stable. Residues lacking alkyl esters did accumulate through hydrolysis of precursors, however. As noted previously, this may positively bias cocaine utilization estimates based on benzoylecgonine alone. Reported variability in metabolic excretion was used in conjunction with transformation data to evaluate different approaches for estimating cocaine loading. Results indicate that estimates derived from measurands that capture all major cocaine metabolites, such as COCtot (the sum of all measurable metabolites) and EChyd (the sum of all metabolites that can be hydrolyzed to ecgonine), may reduce uncertainty arising from variability in metabolite transformation and excretion, possibly to ≈ 10 % RSD. This is more than a two-fold reduction relative to estimates derived from benzoylecgonine (>26 % RSD), and roughly equivalent to reported uncertainties from sources that are not metabolite-specific (e.g., sampling frequency, flow variability). They and other composite measurands merit consideration from the sewage epidemiology community, beginning with efforts to evaluate the stability of the total cocaine load under realistic sewer conditions.

Abstract
BACKGROUND Selling of single cigarettes, also known as loosies, is a public health concern. Loosies allow for those with fewer resources to buy cigarettes without having to purchase a pack. Selling of loosies may cue smoking behaviors. In the US, socioeconomically disadvantaged populations have high rates of smoking and illicit drug use and the selling of loosies appears to be linked to the urban informal economy. We examined the proportion and frequency of cigarette selling and roles in the informal economy associated with selling loosies among a sample of urban drug users. METHODS There were 801 participants, recruited by community outreach, assessed at baseline, who were enrolled in an HIV prevention intervention for drug users. RESULTS Most (89%) smoked cigarettes in the prior 30 days, of whom 92% smoked daily. Self-reported selling of cigarettes was common with 58% reporting that they had sold cigarettes within the last six months; 20.4% reported selling cigarettes a few times a week and 7.4% reported daily selling of cigarettes. In a stepwise regression model, four sources of income were associated with frequent cigarette selling: providing street security (OR=2.214, 95% CI 1.177-4.164), selling food stamps (OR=1.461, 95% CI 1.003-2.126), pawning items (OR=2.15, 95% CI 1.475-3.135), and selling drugs (OR=1.634, 95% CI 1.008-2.648). CONCLUSION There is a high rate of selling loosies among urban substance users. The wide availability of loosies may promote smoking. Smoking cessation programs with drug treatment and economic development programs may help to reduce economic pressures to sell loosies.

Abstract
INTRODUCTION Individuals dependent on alcohol or illicit drugs are vulnerable to cigarette smoking and related adverse health outcomes. Less research has been conducted regarding whether these same groups are vulnerable to smokeless tobacco (ST) use. The goal of this study is to examine vulnerability to ST use among individuals with other drug dependence. METHODS Utilizing the most recent (2011) National Survey on Drug Use and Health (NDSUH), we determined odds ratios (ORs) for current cigarette smoking and ST use among those with current alcohol, cocaine, heroin, and marijuana dependence, adjusting for relevant sociodemographic characteristics. Vulnerability to cigarette smoking was assessed to confirm that alcohol and illicit drug dependence were associated with increased smoking in these data sets, as shown in prior studies. Identical analyses were completed in the 2009 and 2010 NSDUH to assess generality. RESULTS Odds for current cigarette smoking were increased for each category of dependence (p < .0005): alcohol (OR with 99% CI = 3.30 [2.58, 4.21]), cocaine (OR = 4.50 [1.53, 13.20]), heroin (OR = 7.84 [1.92, 32.03]), and marijuana (OR = 3.55 [2.59, 4.88]). Odds for current ST use were also increased among those with alcohol dependence (OR = 1.56 [1.06, 2.30], p = .003) but not illicit drug dependence. Generality of the findings was confirmed in the 2009 and 2010 NSDUH. CONCLUSIONS Consistent with earlier reports, alcohol and illicit drug dependence are associated with robust increases in risk for cigarette smoking. In the case of alcohol dependence, but not illicit drug dependence, this vulnerability also extends to ST use.

Abstract
INTRODUCTION Injection drug use and cigarette smoking are major global health concerns. Limited data exist regarding cigarette smoking behavior and quit attempts among injection drug users (IDUs) in low- and middle-income countries to inform the development of cigarette smoking interventions. We conducted a cross-sectional study to describe cigarette smoking behavior and quit attempts among IDUs in Tijuana, Mexico. METHODS IDUs were recruited through community outreach and administered in-person interviews. Multivariable Poisson regression models were constructed to determine prevalence ratios (PRs) for quit attempts. RESULTS Of the 670 participants interviewed, 601 (89.7%) were current smokers. Of these, median number of cigarettes smoked daily was 10; 190 (31.6%) contemplated quitting smoking in the next 6 months; 132 (22.0%) had previously quit for ≥1 year; and 124 (20.6%) had made a recent quit attempt (lasting ≥1 day during the previous 6 months). In multivariable analysis, recent quit attempts were positively associated with average monthly income (≥3,500 pesos [US$280] vs. <1,500 pesos [US$120]; PR = 2.30; 95% CI = 1.57-3.36), smoking marijuana (PR = 1.38; 95% CI = 1.01-2.90), and smoking heroin (PR = 1.85; 95% CI = 1.23-2.78), and they were negatively associated with number of cigarettes smoked daily (PR = 0.96; 95% CI = 0.94-0.98). CONCLUSIONS One out of 5 IDUs attempted to quit cigarette smoking during the previous 6 months. Additional research is needed to improve the understanding of the association between drug use patterns and cigarette smoking quit attempts, including the higher rate of quit attempts observed among IDUs who smoke marijuana or heroin compared with IDUs who do not smoke these substances.

Abstract
UNLABELLED Tobacco use is a commonplace phenomenon in our society. Its use is responsible for more death and disease than any other noninfectious cause. More deaths are caused each year by tobacco use than by all deaths from HIV, illegal drug use, alcohol use, motor vehicle injuries, suicides, and murders combined. Tobacco remains responsible for greater morbidity than alcohol and all other drugs combined. Tobacco dependence is highly prevalent among drug-dependent patients. Substance abuse patients smoke more and are more vulnerable to the effects of smoking than general populations. Traditional substance abuse therapeutic programs too frequently focus only on treatment of alcohol or other drugs rather than including treatment for tobacco dependence. Currently, there are no official medical recommendations for the treatment of tobacco addiction in illicit polysubstance users. METHODS A comprehensive literature search from a range of electronic databases (PubMed, Embase, PsycInfo, Google Scholar) was conducted for the period from 1988 to September 2012, using the following keywords alone or in combination: tobacco, nicotine, cocaine, cannabis, amphetamines, opiates, substance abuse, substance dependence, addiction, treatment. There were no restrictions on the identification or inclusion of studies in terms of publication status, language and design type. RESULTS Our literature review will focus on epidemiological, neurobiological, clinical interactions between tobacco, alcohol and other illicit drugs. It will also focus on therapeutic programs in this dual addictive disorder. The aim of this literature review is to make proposals for the treatment of tobacco addiction in polysubstance users entering in specific therapeutic programs.

Neurosci Lett 2013; 541:258-62. [PMID: 23510745 DOI: 10.1016/j.neulet.2013.02.049] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2012] [Revised: 01/31/2013] [Accepted: 02/18/2013] [Indexed: 01/28/2023]
Abstract
By balancing the ratios of dopamine and norepinephrine, dopamine beta hydroxylase (DBH) plays an important role in brain reward circuit that is involved with behavioral effects of heroin addiction. DBH -1021C/T (rs1611115) is a functional variant with strong correlation with plasma DBH activity and several nerval and psychic disorders. In the present study, we have collected 333 male cases with heroin addiction and 200 male healthy controls to explore the role of -1021C/T in heroin addiction. There is no evidence of association between -1021C/T and heroin addiction on both genotype and allele levels (P>0.05). In the injection subgroup of cases, -1021TT carriers have longer heroin addiction time (P<0.001) and higher dosage of self-administered heroin (P=0.045) than carriers with -1021CC or -1021CT, suggesting that patients with TT genotype are likely to have more progressive style of heroin users with injection route. In conclusion, our results support -1021TT genotype may be implicated with a more progressive nature of heroin addiction, although DBH -1021C/T is unlikely to be involved in the risk of heroin addiction.

Harrell PT, Mancha BE, Petras H, Trenz RC, Latimer WW. Latent classes of heroin and cocaine users predict unique HIV/HCV risk factors. Drug Alcohol Depend 2012; 122:220-7. [PMID: 22030276 PMCID: PMC3309123 DOI: 10.1016/j.drugalcdep.2011.10.001] [Citation(s) in RCA: 77] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2011] [Revised: 09/30/2011] [Accepted: 10/02/2011] [Indexed: 01/02/2023]
Abstract
BACKGROUND Patterns of heroin and cocaine use vary and may be associated with unique risk factors for bloodborne infections. METHODS Latent class analysis identified sub-populations of 552 heroin and cocaine users in Baltimore, Maryland. Using latent class regression, these classes were analyzed for associations with demographic characteristics, risky behaviors, Hepatitis C, and HIV. RESULTS Three classes were found: Crack/Nasal-Heroin users (43.5%), Polysubstance users (34.8%), and Heroin Injectors (21.8%). Compared to Polysubstance users, Crack/Nasal-Heroin users were almost 7 times more likely to identify as Black (OR=6.97, 95% CI=4.35-11.2). Sharing needles was over 2.5 times more likely among Polysubstance users than among Heroin Injectors (OR=2.66, 95% CI=1.49-4.75). Crack/Nasal-Heroin users were 2.5 times more likely than Polysubstance users to exchange drugs for sex (OR=2.50, 95% CI=1.22-5.13). Crack/Nasal-Heroin users were less likely than Heroin Injectors to have Hepatitis C (OR=0.10, 95% CI=0.06-0.18), but no significant differences were found for HIV. CONCLUSIONS Subpopulations of cocaine and heroin users differed in demographic classifications, HIV-risk behaviors, and Hepatitis C infection. All subpopulations included substantial numbers of HIV-positive individuals. Findings provide further evidence that non-injection drug users face significant infectious disease risk.
